If you're low on cash and high on resourcefulness, you may find this guide handy. X-bit Labs has put up a guide to modding the Radeon X800 Pro into a Radeon X800 XT.

Quote:

Some RADEON X800 PRO graphics processors can be modified into the RADEON X800 XT chips, whereas others cannot, as quite a lot of unlucky experiences revealed. Even though the yields of the RADEON X800 PRO seem to be pretty fine, yields of graphics processors with 16-pipelines deserve better, as a result, only a part of ATI RADEON X800 PRO products can really be turned into more powerful solutions.

OK, all I need now is a Radeon X800 Pro card and I'm ready to do this! News spotted on VE3D.com.
